If you are new to portable cofferdams, then you are probably wondering what types of equipment you need when it comes to competing the installation of one. Perhaps you have always previously used more ‘traditional’ methods for your water displacement needs, such as the construction from steel or concrete of temporary dams. Perhaps you are installing a portable cofferdam for the first time, and you want to learn the best way of doing so, and the most efficient level of equipment required to complete the task in the minimum of time and with the minimum of effort.

The good news is that your friends at Dam-It-Dams are here to help. We have been installing portable cofferdams now for over two decades and have become extremely efficient in doing so. We are now ready to share our knowledge with you.

Material Required to Install a Portable Cofferdam

The cofferdam itself

Of course, you need the cofferdam itself if you intend to install one. You can rent one for a single-time use or, if your company repeatedly finds itself tasked with construction projects and repairs in or close to water, then it will be more cost-effective for you in the long term to purchase one. If you take care of it, a portable cofferdam will serve you well for many repeated uses.

Water discharge pumps

You do not need industrial-sized pumps in order to inflate an inflatable cofferdam. Any pump capable of pumping water for an extended period will do. The size and capacity of the pump and the number of pumps you use is up to you, but of course the more powerful the pump(s) and the more you use, the quicker the inflation time.

Discharge and suction hoses

You will not be able to directly connect the pumps to the cofferdam, so you will need suitable hoses for each pump.

Restraining ropes

With static water, these are a ‘nice to have’ but in dynamic water they are crucial. You will need to anchor the cofferdam in position during installation. We recommend a minimum of four half-inch ropes, with the length of the rope being 250ft in length per 100ft of cofferdam.
